Description
Technical field
The present invention relates to communication technical field, more particularly to a kind of uplink dispatch method and device.
Background technology
When ascending-descending subframes number is asymmetric, scheduling subframe, transmission subframe and feedback subframe cannot form one-to-one corresponding and close
System.For example, when sub-frame of uplink number is more than descending sub frame number (include special time slot), the corresponding dispatch of multiple sub-frame of uplink
Need to transmit in same descending sub frame.In this case, up instruction (UL grant) is needed comprising up instruction (UL
Index) domain, for indicating the numbering of corresponding sub-frame of uplink.When sub-frame of uplink number less than descending sub frame number (include it is special when
Gap) when, corresponding confirmation (ACK)/non-acknowledgement (NACK) information of multiple descending sub frames is transmitted in same sub-frame of uplink.This feelings
Under condition, need to indicate (DAI) domain comprising descending distribution in UL grant, for indicating in current uplink ACK/NACK feedback windows
Need the dynamic physical downlink sharied signal channel (Physical Downlink Shared Channel, PDSCH) of feedback
The summation of number and descending semi-continuous scheduling (Semi-Persistent Scheduling, SPS) release signaling number, is used for
Judge in uplink ACK/NACK feedback windows whether packet loss.
Therefore, UL index, are served only for scheduled time division duplex (Time Division Duplex, TDD) uplink-downlink configuration 0
Physical uplink link shared channels (PUSCH), for indicating the numbering of corresponding sub-frame of uplink.And DAI, it is current for indicating
The number and the summation of descending SPS release signalings number of the dynamic PDSCH of the needs feedback in uplink ACK/NACK feedback windows,
For judging in uplink ACK/NACK feedback windows whether packet loss.
In existing TDD system, UL index domains are present only in uplink-downlink configuration 0, and DAI domains are only in up-downgoing
Exist during configuration 1-6.Therefore, always only comprising one of domain in UL grant (DCI 0 and 4) information.
But with the development of technology, the promotion of particularly following three kinds of technologies, the corresponding dispatch of multiple sub-frame of uplink
In same descending sub frame, transmission and the corresponding ACK/NACK information of multiple descending sub frames are transmitted in same sub-frame of uplink
Situation may be simultaneously present, and current downlink control information (Downlink Control Inion, DCI) design cannot support this
The situation of kind.
First, dynamic TDD.
It is as the tdd mode of one of two big basic duplex systems, ever-increasing to bandwidth demand in wide-band mobile communication
It is under background, of increased attention.Uplink and downlink transmission in TDD system uses identical frequency resource, in difference
Time slot on transmit uplink/downlink signals.In common TDD system, including the time division synchronous of the third generation (3G) communication system
CDMA accesses (Time Division Synchronized Code Division Multiple Access, TD-
SCDMA) time-division Long Term Evolution (the Time Division-Long Term of system and forth generation (4G) communication system
Evolvement, TD-LTE) system, the division of uplink and downlink time slot is static or semi-static, it is common practice in net
Determine unified uplink and downlink timeslot ratio and keep constant according to business proportion substantially in network planning process.This is big in macrocell
It is relatively simple way under the background of covering, and it is also more effective.And as technology develops, increasing Microcell
The low power base stations such as (Pico cell), Home eNodeB (Home NodeB) are deployed for providing the little covering of local.One side
Face, the main type of service of this kind of cell (for example, data service) are different with macrocell (for example, speech business), therefore, up and down
The proportioning demand difference of row time slot is larger.On the other hand, the number of users of this kind of cell is less, and customer service changes in demand compared with
Greatly, thus cell up-downgoing business proportion demand exist dynamic change situation.Based on this, up-downgoing is more dynamically configured
Time slot ratio receives more concerns and studies.
2nd, (inter-band) TDD in frequency band.
In advanced Long Term Evolution (LTE Advanced, LTE-A) system, the peak rate of system has huge than LTE
Raising, it is desirable to reach descending 1Gbps, up 500Mbps.If a use of maximum bandwidth being only nothing for the carrier wave of 20MHz
Method reaches peak-rate requirements.Therefore, lte-a system needs the bandwidth that terminal extension can be used, and thus introduces carrier wave
Polymerization (Carrier Aggregation, CA) technology, multiple continuous or discrete load that will be under same eNB (base station)
Ripple condenses together, while service for UE, with the speed needed for providing.These carrier waves for condensing together are also called member carrier
(component carrier, abbreviation CC).Each cell can be a member carrier, the cell (member under different eNB
Carrier wave) can not be polymerized.In order to the UE for ensureing LTE can work under each carrier wave being polymerized, each carrier wave maximum is less than
20MHz.The CA technologies of LTE-A are as shown in figure 1, have 4 carrier waves that can be polymerized, base station can simultaneously 4 under the base station of LTE-A
Carry out data transmission with UE on individual carrier wave, to improve throughput of system.
In LTE versions 11 (Rel-11) or the later system of version, in order to avoid the interference to other TDD systems, it is located at
The LTE cells of different frequency bands (Band) may use different TDD uplink/downlink sub-frame configurations, as shown in Fig. 2 wherein 1 He of carrier wave
Carrier wave 2 is located at Band A, and carrier wave 3 is located at Band B, and cell 1, cell 2 and cell 3 are on carrier wave 1, carrier wave 2 and carrier wave 3 respectively
Cell.Cell 1 is identical with the TDD uplink-downlink configurations of cell 2, is configuration 1, the TDD uplink/downlink sub-frame configuration of cell 3 with
Cell 1 and cell 2 are different, are configuration 2.If terminal is desirable with these three cells and carries out carrier aggregation, then just occur
The different situation of the TDD uplink-downlink configurations of all aggregation cells of terminal.
3rd, FDD (FDD) is polymerized with TDD.
TDD carrier waves and descending (DL) carrier aggregations of FDD may be supported in the follow-up evolution systems of LTE.
In sum, DCI of the prior art cannot support the corresponding dispatch of multiple sub-frame of uplink same simultaneously
The situation that transmission and the corresponding ACK/NACK information of multiple descending sub frames are transmitted in same sub-frame of uplink in individual descending sub frame.
